I am having a similar issue on my environment (the availability report takes about 5 minutes to generate, which is especially frustrating since what I need to run it for is not the default parameters). I figure I would post here as I don't see what the eventual fix was for the other users experiencing the issue.

Nagios version: 2014 R2.7 ... in process of being upgraded to 5.3.0 :)
Nagios db: not offloaded
Specs: 4 vcpu 8 GB RAM 200GB HD
Availability report contains approx 20-50 hosts for a time period of prior month

Can you monitor top during one of these timeperiod for generating an availability report? Please use this command and paste the output:

Code: Select all

# SECONDS=0; while [ ${SECONDS} -lt '301' ]; do top -bcn1|head -n20; sleep 30; done
Also what is the output of this during an availability generation:

Code: Select all

for file in /proc/*/status ; do awk '/VmSwap|Name/{printf $2 " " $3}END{ print ""}' $file; done | sort -nrk 2
and the output of this:

Code: Select all

df -h

Here you go - didn't quite run 5 minutes so I stopped the top once the report finished.

You have an awful lot running on that system. Nagios XI is design to be used on clean installs for a server eg no GUI. The system swap is also in use, this will effect system speed in multiple ways. You can try to free up some memory by disabling unneeded components, or just increase the memory in the system.
Maximizing Performance In Nagios XI

At least several of those steps may greatly improve your performance although they can hurt it as well if the system is too low in memory.

I increased the memory but it didn't seem to make any difference in the speed of the report. There was still 6GB free memory so I don't think it's the bottleneck.

Maybe my expectations are just out of line for this? Is the availability report expected to run for a few minutes on a system of my size?

We are planning an upgrade and then migration to the 5.3.0 OVA to remove the overhead of the unneeded services on the current build and to get code current. I can test again afterwards to see if the performance is any better.

Thanks

No it shouldn't take that long for a system of your size. As noted in the referenced thread, the time to generate the report is almost entirely driven by disk IO. Is that abnormally slow for some reason eg slow disk, network storage, etc?

Can you download the CSV of the report and let us know how long it takes?

XI > Admin > System Profile > Download Profile

Please include the zip file in your response. You can PM myself or other support personnel if you have privacy concerns.

Also please send a screen of XI > Admin > Monitoring Engine Status

FYI, 5.3.2 is the current release.

For the default availability report, CSV: hosts = 28 sec, services = 1:49. Web view is 2:16.
Sys profile and monitoring screenshot attached

edit: also, it is running on our tier 1 SSD backed SAN, so there should be no issue with disk access speeds.

Thanks

Apache is reporting strange periodic error like this: incomplete redirection target of '/nagiosxi/' for URI '/' modified to 'http://10.100.224.121/nagiosxi/

At this point since you're planning an upgrade anyways, let's do that first as a rather significant amount of things have changed under the hood.

Remember do the upgrade first, use this process: https://assets.nagios.com/downloads/nag ... nstall.pdf

For the migration, use this: https://assets.nagios.com/downloads/nag ... ios-XI.pdf

For best results, restore on to a clean install of CentOS/RHEL 6/7 minimal. Only addition rpm needed to bootstrap is wget.

Let us know if that helped or not.

Ok, will do.
The apache error is probably caused by a customization I did that redirects / to /nagiosxi/ for convenience

Re: availability reports slow

Posted: Wed Nov 02, 2016 2:50 pm

That line likely needs http://10.100.224.121/ in front of the target URL then, plus an apache restart.

As a general rule, anything in the error_log shouldn't be there.
